Description
Technical field:
The utility model relates to elevator technology field, particularly relates to a kind of elevator hydraulic damper.
Background technology:
For the water bumper of the equipment such as elevator, utilize hydraulic damping effect to carrying out buffer deceleration at the car or counterweight of doing coast to stopping, namely when elevator surmounts bottom or top layer, car or counterweight cushion at collision, absorbed or consume the energy of elevator by energy disperser, thus make car or counterweight be decelerated to stopping safely.
The essential structure of now conventional water bumper comprises base, be arranged on the inner casing on base and outer shell, be placed in the piston of interior cylinder interior, connect the piston rod of piston, and be arranged at the sealing arrangement at outer shell top, and piston rod passes sealing arrangement and is connected to piston, upper cover of piston rod is provided with the spring resetted for piston rod, and interior casing wall is provided with cutoff port and plays buffer action for passing through of hydraulic oil.
As publication technology, the patent No. is a kind of water bumper of 201210172729.8, comprise: base, outer shell, inner casing, sealing arrangement, piston, piston rod and spring, described inner casing is hollow form and cylinder body is provided with oilhole, and described oilhole is that inner casing is axially evenly arranged; The pore size of described oilhole not etc., and is not distributed on the cylinder body of described inner casing.It is the inner oil circulation formula of twin-tub, the cylinder body of its inner casing is designed with the oilhole of right quantity different pore size, different oil masses of rushing down is produced according to elevator payload ratings and command speed, thus the damping needed for producing reaches the object of buffering, is applicable to the elevator of different payload ratings and command speed.But because oil spillage during throttling is fixed in actual use procedure, thus not there is universality; In addition, due to cutoff port skewness, thus cause in buffering course, there is the uneven problem of buffering stop power.
Therefore, for solving the problem, be necessary the elevator hydraulic damper that a kind of improvement is provided.
Utility model content:
The purpose of this utility model is to provide a kind of elevator hydraulic damper, and its deceleration/decel that better can solve the buffering stop of elevator compares uniformity problem.
The utility model is for solving above technical matters, adopt following technical scheme: a kind of elevator hydraulic damper, comprise outer cylinder body, piston cylinder, piston cylinder protecgulum, piston cylinder bonnet, piston cover plate and piston rod, outer cylinder body upper end connects the lower surface of piston cylinder bonnet, lower end connects piston cover plate and forms a sealed cylinder block, piston cylinder lower end connects the upper surface of piston cylinder bonnet, upper end connects piston cylinder protecgulum and also forms storage oil mass sealed cylinder block, it is characterized in that: piston rod upper end is fixedly connected with piston ring, and be located in piston cylinder, lower end passes outer cylinder body, and connect damping rubber pad in its end, the sidewall of described piston rod upper end is provided with oilhole, the position corresponding with oilhole is provided with current limliting pad, current limliting pad coordinates with piston cylinder inwall and contacts, described piston rod moves along piston cylinder inwall, the effect of damping is realized by the oil mass volume of current limliting pad change piston cylinder.
Described piston cylinder is made up of piston inner casing and piston outer shell, the wall thickness of the wall ratio piston outer shell of described piston inner casing is thick, one end of piston outer shell connects oil cylinder front cover, the other end is connected with the upper surface of piston cylinder bonnet, piston inner casing one end connects oil cylinder front cover, and the other end is connected with piston cover plate.
The utility model adopts above technical scheme, compared with prior art has following technique effect:
Because piston rod is provided with current limliting pad corresponding to oilhole, keep basicly stable, to make the deceleration/decel of buffering stop more even making the oil pressure of damper (namely cushioning stop power).
